Abstract
Twenty-four years ago the first industrial gas-turbine unit, a Brown Boveri 4000 kW set installed by the City of Neuchâtel in Switzerland, started a new era of power generation. This new type of prime mover has since been widely introduced and generally accepted. It serves as base-load and as peaking plant. The fuels used range from natural and blast-furnace gases to diesel, crude, and heavy fuel oils. Extensive experience of running has accumulated in all applications which has permitted the analysis of the operating performance of the gas turbine.
The paper reports on the performance of some characteristic gas-turbine installations that are representative of the different applications and fuels.
In addition to providing interesting information on the general performance of the gas turbine, the experience gained under various conditions has also permitted the discovery, understanding, and control of special design problems not previously recognized. The more important of those discovered in recent years are discussed and corrective measures are explained.
